Extendible Web Service

To introduce our business, we run a number of trading companies in different countries, currently two companies one in Australia and the other in Hong Kong. However in the near future we will open other companies in other countries to extend our trading business. We sell our products on a number of platforms like Neto ([login to view URL]), Shopify, Ebay and our own websites. To keep track of the performance of the different companies, we would like to report the sales orders to the accounting files referring to the company responsible for that sale. Currently we use Onesaas to consolidate our sales order from the different selling platforms, and send it to our accounting files on Sassu ([login to view URL]) which is our accounting software. We are planning to have a software which will include several web services for different functionalities, but based on our priorities we will start now with version 0.1 which of highest priority for us right now, however if you commit to build this version 0.1 it will have to be ready for extending by you or any other freelancer in the future. Version 0.1 description: -This version will be simply pulling sales orders from one specific sales platform Neto ([login to view URL]). -Sales orders pulled from Neto ([login to view URL]) refers to two different eBay store names, one for each company. -Our web service then should filter orders pulled from Neto ([login to view URL]) based on eBay store name. -Sales orders belonging to each company should be then pushed to the correct corresponding Sassu ([login to view URL]) accounting file. -Both manual and automatic (periodic every hour) options to pull and push information from Neto to Sassu should be available. -User Should be able to add visually (not in code) information needed to connect to Neto or Sassu. Version 0.1 requirements: -Develop a software to include a Web service meeting the project description -Use a programming language/framework appropriate for this project and suitable for the freelancing culture, putting in mind this project will be extending in the future by you or possibly other freelancers. -In code documentation is highly important -Include a web page with simple basic design (bootstrap). Please get back to me with brief background about your self, proposed programming language/platform, number of hours needed and a brief simple overview on the flow of the project. Thanks
